Help needed on DEM extraction

[sktangel at cedrus.ecn.uoknor.edu]

Hi friends,
	I have been trying to extract DEMs in to a lat-long location. The DEMs  I am working on are of 1:250,000 scale, and are the ones produced by USGS. In UTM region I followed the following set of commands :

	1. "dd if=..."|m.dmaUSGSread ...
	2. m.rot90
	3. r.in.ll
	The last command would put the DEM in my location in raster format. But when I tried the same proceedure with lat-long the resulting DEM was totally distorted. Well, actually it did'nt look like a DEM. Can any one solve my problem.

thanks,
Sree.
